Society must revisit the currently dominant agricultural production model based on land expansion and intensification. Greenhouse cultivation represents a promising alternative, particularly in the Global South.
Model projections suggest that, even under a low-emissions scenario, lakes on the Tibetan Plateau will increase in area by about 50% by 2100, with widespread impacts on infrastructure and ecosystems.
Explosive volcanic eruptions of Kīlauea in Hawaii can be explained by sudden subsidence of reservoir roof rock causing gas and lithic debris venting by a mechanism similar to that of a stomp rocket, according to seismic inversions for reservoir pressure changes.
A combination of anthropogenic warming and natural variability led to another record-breaking year of warmth in 2023. Global mean temperatures in 2023 nearly exceeded the 1.5 °C threshold, making it both a scientific and societal imperative to understand the underlying reasons for this warmth.

Wildfires have increased in frequency and intensity due to climate change and have had severe impacts on the built environment worldwide. Moving forward, models should take inspiration from epidemic network modeling to predict damage to individual buildings and understand the impact of different mitigations on the community vulnerability in a network setting.
Wildfires burned 384 Mha of land in 2023, the highest since 2017 but 5% lower than the 2001–2022 average. These fires emitted an estimated 2,524 Tg C, 30% of which came from Canada’s record fire season.
